ECG INTERPRETATION TUTORIAL

T Wave

The T wave occurs after the QRS complex and is a result of ventricular repolarization. T waves should be upright in most leads; the exceptions are aVR and V1. Further, T waves should be asymmetric in nature. The second portion of the T wave should have a steeper decline when compared with the incline of the first portion. If the T wave appears symmetric, cardiac pathology such as ischemia may be present.
